CVE-2011-2178: Red Hat Libvirt

Medium severity, CVSS 4.4. EPSS: 0.3% chance of exploitation in the next 30 days.

The virSecurityManagerGetPrivateData function in security/security_manager.c in libvirt 0.8.8 through 0.9.1 uses the wrong argument for a sizeof call, which causes incorrect processing of "security manager private data" that "reopens disk probing" and might allow guest OS users to read arbitrary files on the host OS. NOTE: this vulnerability exists because of a CVE-2010-2238 regression.

Affected products

• Red Hat Libvirt: version 0.8.8 only; version 0.9.0 only; version 0.9.1 only
